Rear Coil Springs on 1998 Toyota Sienna

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
What needs to be done to change out the rear coil springs on a 1998 Toyota Sienna. Are there any bolts or do I just use a decompression tool then jack the vehicle up.

You can use a spring compressor if you support the rear axle with a jack and remove the shock you should be able to lower the axle far enough to just pull the spring out.

Do one side at a time it will make lowering/raising the axle easier.
